California Nuts California’s three-year drought may be changing the future of the state’s agriculture. Farmers in Yolo County growing row crops like tomatoes and plums are tearing up the plants and replacing them with nut trees. Walnut, almond and pistachio trees produce a higher yield than row crops for the same amount of water and the market for California nuts is booming right now as demand grows around the world. Joining us to explain what's happening with the state's different nut growers are Bruce Lampinen, an almond and walnut specialist at UC Davis who specializes in water relations, Louise Ferguson, a University of California Cooperative Extension specialist in pistachios, and Jack Mariani, a walnut grower in Winters.
